Dolby Laboratories and Texas Instruments Collaborate on World’s First 1394 Hardware to Connect Personal Computers to Home Theater SystemsSan Francisco, March 13, 2003--Dolby Laboratories and Texas Instruments
Incorporated (TI) (NYSE:TXN) announced they have jointly sponsored the design and
development of a device that allows consumers to easily connect PCs with 1394
connectors to their home theater systems.

The Firewire™-S/PDIF converter allows Dolby® Digital and PCM audio to be
transferred from a network of IEEE 1394 devices (which may include laptops and
desktop PCs) to the S/PDIF connection commonly found on today's home audio
equipment. This allows music and gaming enthusiasts to play back popular stereo and
multichannel 5.1 computer music files, such as MP3, AAC, and WMA, through their
home theater systems from their PCs. A prototype implementation of this design was
shown at Texas Instruments' booth at the Consumer Electronics Show (CES) in January.

The converter, created by Island Digital Media Group, consists of an IEEE 1394
connector at one end and a coaxial S/PDIF connector at the other. It requires no
additional wires if power is available from the 1394 cable, though a DC connector is
available on the device for an external power supply, if needed. The device runs on a
Texas Instruments iceLynx-micro (TSB43CB43A) chip.

IEEE 1394, also known as Firewire and iLink™, was designed to be a universal
connection between electronic devices, including camcorders, personal computers,
digital televisions, A/V receivers, DVD players, printers, and so on. Different types of
digital signals can be carried on 1394 cables, including video, audio, MIDI, device
control commands, and computer data. Though A/V equipment with 1394 is beginning
to appear on the market, the vast majority of gear in people's homes still relies on the
S/PDIF connector as the link to digital audio. PCs, on the other hand, are far more likely
to have a 1394 connector than a S/PDIF connector, making it difficult to send digital
audio (such as a DVD soundtrack from the PC) to the primary listening equipment in
the home. The Firewire-S/PDIF converter allows consumers to easily enjoy stellar
digital audio entertainment from their PCs.

"Entertainment PCs have, for years, had the ability to output graphics and video to
televisions; now they can finally enjoy high-quality stereo and 5.1-channel surround
sound audio playback from their companion home theater systems," said Bob Brummer,
director of technology strategy at Dolby Laboratories. "Because Dolby is prevalent in
both consumer electronics and PC entertainment, Dolby Digital is an obvious choice for
compelling audio entertainment that can bridge the gap between these environments. As
home networks grow in popularity, PCs will play a more prominent role as home
entertainment platforms. Simplifying and enabling the connection of PCs to traditional
CE devices gives the consumer new ways of enjoying music and gaming
entertainment."

"TI's iceLynx-micro was designed and tailored for the audio entertainment market," said
Belal Ahmad, consumer electronics product manager for TI's Connectivity Solutions
group. "The Firewire-S/PDIF converter taps into the millions of 1394 PCs and S/PDIFenabled
home theater systems and addresses the growing demand to easily connect PCs
to home theater systems so consumers can enjoy private music collections."

"We are delighted to work with industry leaders such as Dolby and Texas Instruments to
develop this critical link," said Bob Moses, president of Island Digital Media Group.
"We look forward to working with OEMs to bring it to the marketplace."
